3. The system of claim 2, wherein the first customer information does meet the trigger condition and the first price for the product is the discounted price.

6. The system of claim 2, wherein the first data cache, the second data cache, and the third data cache exist on a single physical memory structure.

7. The system of claim 2, wherein the first data cache, the second data cache, and the third data cache comprise separate physical caches.

8. The system of claim 7, where the first data cache, the second data cache, and the third data cache are level 2 external caches.

9. The system of claim 2, wherein each of the data caches has a time-to-live duration, and further wherein the time-to-live duration for the first data cache is longer than the time-to-live duration for the third data cache, and wherein the time-to-live duration for the third data cache is longer than the time-to-live duration for the second data cache.

10. The system of claim 9, wherein the time-to-live duration for the first data cache is longer than one hour.

11. The system of claim 10, wherein the time-to-live duration for the third data cache is less than one minute.

14. The system of claim 13, wherein the pricing engine computer stores the product information in a product cache for later retrieval of the product information without requiring an additional request to the product database.

15. The system of claim 14, wherein the pricing engine computer stores the offer information in an offer cache for later retrieval of the offer information without requiring an additional request to the offer repository.

17. The method of claim 16, wherein the first customer information does meet the trigger condition and the first price for the product is the discounted price.

19. The method of claim 16, wherein the first data cache, the second data cache, and the third data cache exist on a single physical memory structure.

20. The method of claim 16, wherein a time-to-live for the first data cache is longer than a time-to-live for the third data cache, and wherein the time-to-live for the third data cache is longer than a time-to-live for the second data cache.
